Also, Screwfix stock a plastic pipe system by FloPlast (Flo-Fit) at a

Check the temperature and pressure ratings. The pressure rating drops
dramatically as the temperature rises.

Is that likely to be a problem with any of the plastic plumbing systems
though and even a pressurised system is only run at 1 bar or so. Hep2O
and Speedfit are fine.

If you've got mains pressure hot water, that can get a fair bit over 1
bar. (Without checking the ratings, I don't know if it's likely to be a
problem.)

Temporary fit Speedfit here - 4.5bar pressure on the hot water side, up to
60C, no problems.
